Rare Earths Supply

While not a current producer of REEs, Canada has some of the most advanced exploration projects in the world. Canada hosts 20 of the 63 advanced REEs projects tracked by Technology Metals Research, a company focused on markets and analysis of critical and strategic materials such as REEs.

REEs are categorized as being either “light” or “heavy”:

  • Light REEs (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium and scandium) are produced in global abundance and are in surplus supply
  • Heavy REEs (terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and yttrium) are produced mainly in China and are in limited supply. Global efforts to bring new resources to the marketplace continue.

Many of Canada’s most advanced REEs exploration projects contain high concentrations of the globally valued heavy REEs used in high-technology and clean-energy applications.
